模型参考自适应控制系统的稳健性分析

Robustness Analysis of Model Reference Control Systems

本文对高频寄生,外部干扰及高频参考输入共存的模型参考控制系统进行了稳健性分析。采用Narendra直接法设计思想,利用Ioannou修改的自适应律,给出了状态偏差,寄生变量和失配参数向量的有限上界。

In this paper, robustness of model reference adaptive control systems in the presence of high freqency parasitics, external disturbances and high freqency reference input is analysed. Narendra's idea of adaptive controller design is adopted; direct method and modified adaptive law of Ioannou is used, finit upper bounds of state error, parastitics state and mismatch parameter vector are established.
